摘要： The invention relates to an improved control method for an air conditioner (1) of a vehicle, in particular a motor vehicle, wherein the air conditioner comprises the following: a fan (2); a temperature control device (3) for controlling the temperature of the air in the fan (2) and/or flowing out of the fan (2); an air distribution system (4) for distributing the air mass flow caused by the fan (2) via a plurality of air channels (4a-4d) to associated air discharge openings (9a-9d); a plurality of motorized adjustable throttle flaps (5a-5d) for influencing the flow resistance in the air channels (4a-4d); and control electronics (6) having a user interface (11), wherein the method comprises the following: analyzing the setting of the user interface (11) for providing air mass values specific to the adjustment for the individual air channels (4a-4d) and selecting particular air channels (4a-4d) as a function of the adjustment; determining which air channel (4a-4d) has the greatest pressure loss in the unthrottled setting of the associated motorized adjustable throttle valve (5a-5d) out of the selected air channels (4a-4d); determining a required system pressure for the particular air channel (4a-4d) having the greatest unthrottled pressure loss; controlling the fan power as a function of the required system pressure and as a function of the sum of the air mass values of the selected air channels (4a-4d); determining the throttle flap settings of the selected air channels (4a-4d) using the air mass values specific to the settings, such that the required system pressure is achieved, wherein the throttle flap settings of said air channel (4a-4d) out of the selected air channels having the greatest unthrottled pressure loss are the unthrottled setting; setting the throttle flaps (5a-5d) to the associated, previously determined throttle flap settings.
